d)7x=-21
e)13x=13
f)9x=-9
g)25x=0
h)35x=-105
i)4x=1
j)36x=12
l)21=3x
m)84=6x​

Answer 1

Resposta:

a) 3x =15

x = 15/3

x= 5

b) 2x=14

x= 14/2

x=7

c) 4x = -12

x = -12/4

x= -3

d) 7x = -21

x = -21/7

x = -3

e)13x = 13

x = 13/13

x= 1

f) 9x =-9

x = -9/9

x= -1

g) 25x = 0

x= 25/0

x= 0

h) 35x = -105

x= -105/35

x= -3

i) 4x =1

x=4/1

x=4

j) 36x=12

x=12/36

x= 0,3333...

l) 21=3x

x = 21/3

x= 7

m) 86=6x

x=86/6

x=14,3333333...
